This experiments compare non-linear models and linear models under Gaussian and Laplacian attributes on three benchmark citation networks PubMed, Cora, and CiteSeer  [1]}. In these three networks, nodes denote papers and edges denote the citation relationships between the papers. The statistics (\(\#\)  nodes, \(\#\)  edges, \(\#\)  classes) of these three networks are: PubMed (19,717, 44,338, 3); Cora (2,708, 5,428, 7); CiteSeer (3,327, 4,732, 6).
